Nothing to special, but it might really be the only example in the USA. In all my research over the years, I've never seen another one here, and I have only seen 1 or 2 on Spanish e bay type sites. I believe the bike is of Spanish origin and was marketed by BH Bikes. I purchased the frame on e bay from Lance Armstrong's shop in Texas. I have no idea who Fabio was or is, but I like his style. Very Colnago-ish. I'd love to find out who he is. I did a full Campy build on her and it is a nice rider.

The frame and fork is certainly rare. I've had this for many years now and spent a lot of time looking for info mostly in Italy and found nothing, not even one bike or frame even close to it. So as far as I know it's the only one.

Originally had a Fusari decal and signature. Fusari is an Italian family name and used to names businesses and sports teams. Bolzano is an Italian city. How the two names come together to name this bike I cant find info on.

I've even contacted Olympia for info about the bike but with no reply.

It's a special bike to ride to me and become my grail bike. Very light but stiff in the bb and pure race bike

Well, all those bikes are beautiful, and Nguyen's is not just "rare", it's unique - one of a kind .
But I don't think that "rare" necessarily implies beauty, or even desirability - Just something very uncommon.
By that definition, this is "rare", but not really beautiful, OR highly desirable (to most people) ...........

Rare is at least obtainable. This is rare but apparently obtainable as fellow BF member and Texan jim dandy has one and there was another in San Antonio. However that's it. The Centurion Ironman had a short five year run ending in '89. And this Color Scheme (Cobalt Blue marble) was never officially offered. The general consensus is that it was slated to be the '90 version.

MacGregor 2 wheel drive mountain bike:

This one is really rare. It's the 1st time for me to see! To me, it's the most beautiful vintage MTB! Congrats!

I have two. A 78 (Shwinn) World, their first import from Taiwan. They didn't claim it by not putting their name anywhere on it, except the quick releases on the brake levers. No idea how many came in, but there are not many left. Mine is in line for a suspension fork and a 27" knobby rear. The other one is a 79 Trek 930, 24". It came to me as a frameset, and I am not particular about period correct or matching components. Or drive side shots, apparently

__________________I just love riding a vintage road bike. The smooth speed and quick response of the steel has to be one of the most enjoyable experiences I know.

Rare, to me, means nothing in the world of vintage road bicycles. Generally, old and I mean pre-1970 road bikes are rare - in North America. and parts for them are equally rare. So, I suppose that my Rabeneick 120d, from the late fifties might be considered to be rare, simply because it is old and not all that many were made...

Suppose that I could argue that my early Quintanna Roo is rare also, but only because it is the only one that I have ever seen in person...

1972 Line Seeker CF/Steel/Al race bike.
It's the only example that I had found so far that is original, intact and rideable. Only things I had to replace was the brake levers, saddle, brake cables and pads and rims on the wheels. The only other one I found was owned by a bicycle museum and it was toast.#22 of supposedly only 300 made (hand made in the designing engineer's residence in 1972). Before Exxon bought the design from the engineer and modified to become the Exxon Graftek.

I have a '76 Bridgestone Superlight 'Ten-Speed'
While Bridgestone's aren't rare, the cast-aluminum Superlight is an odd duck.

All of the Ten-speed Superlight's I've seen have been badged as Kabukis, C.Itohs or (Canandian) SuperCycle, never a Bridgestone.
I've found pictures of 'Bridgestone Superlights' but while they appear to share the same frame, they're fendered 3-speeds with swept bars. And they seem to all be in Thailand, or Vietnam.

This particular example was purchased in Okinawa (in 1976), so that explains the Bridgstone badging, but it's a 57~58mm frame, so probably aimed at the export market rather than the locals.
Pre-restoration, mostly original state:

All I have are a few "Somewhat Rare". So like most of our bikes, only appreciated by bike geeks. Recently got this one based on its unusual frame geometry + low price. 91 Gary Fisher Montare. I examined her seat tube and braze on DR tab carefully, because some cracking/failure problems were reported. Comforting that owner was a trim young fellow who weighed 145 pounds. Plan a renovation this Winter. Don
